Why does not the machine pull: causes?
Modern engines are goodcapacity, sufficient level of economy, less pollute the environment. When the behavior of the power unit is changing, it is immediately noticeable. If the machine does not pull, the causes of this phenomenon can be very different. Let's look at them.
The engine may lose traction for various reasons. There is a huge number of various malfunctions, which result in a loss of power. Sometimes the craving disappears without any symptoms. The unit does not produce unusual noises for it, it does not vibrate - it simply lost its traction. Every day the car goes worse and worse. Probably, this situation is familiar to every motorist.
Low fuel quality
If the machine does not pull, the reasons for this phenomenon can be very different. But the first is the quality of the fuel.Try to remember at which gas station you are inlast time they filled their car. Maybe the fuel is not too high quality? At gas stations sometimes sell such gasoline that the engine and does cease to work, until the tank is empty and there will not be filled with better fuel.
Check the air filter
Too dirty the filter does not passsufficient air to create a fuel mixture. This can lead to a significant drop in engine power, and fuel consumption will increase significantly.
In addition, the quality of the materials used in the engine can influence the work of the motor.Buying the next filter, many try to buy the cheapest products that are only available. You should not buy anything, because the further repair of the motor will be much more expensive.
There are many different stories about cheap andnon-original filters. These products are torn, and then through the chain there is a series of serious malfunctions, up to the failure of the piston rings. To check the condition of the air filter, you need to open the hood, get the element out of the housing and visually assess the condition. If necessary, the part is immediately changed.
Sometimes, while in a certain state,fuel cells do not supply enough fuel to the fuel system of the car. As a consequence, the machine does not pull. The reasons are clear, and to check the fuel filter, it is dismantled, and the remaining fuel is drained.Then it is blown. If the element is clean, then it is very easy to blow. If you blow it out is difficult or impossible, then it should be discarded. Otherwise, the fuel pump will have to be changed in the future.
Pressure in the power system
The fuel pump is located in the gas tank, on theinjector motor. On the carburetor engines, the pump is detected under the hood, on the engine. For most cars, power losses can be associated with a fuel pump.
Many modern cars havespecial connectors on the fuel line for connection of a manometer. So you can check the pressure. If there is no connector, you will have to work a little bit to connect.
Pressure values can be found in the instructions forengine. In the highway there is a special regulator, with which you can drop excess pressure directly into the tank. This regulator may be misconfigured, or it may leak. To check it you will need an ordinary air pump. With it, you need to gradually raise the pressure level to the one indicated in the passport to the motor. If you did not manage to increase the pressure, and the regulator threw fuel into the tank, then it must be replaced.
Here it is necessary to check whetherexposed the ignition lead. Sometimes, if the machine does not pull, the reasons can be precisely this. It is also necessary to check the condition of the spark plugs and high-voltage wiring. For more details on how to perform a test, read the instructions for the specific engine. The main thing here, in troubleshooting, is to use not only your experience. It is also important to analyze similar situations on other cars.
Air flow and pressure sensor
These two elements determine how muchof air consumes the engine, as well as how much air is needed to create the optimal fuel-air mixture. If these sensors fail, then the computer will incorrectly make calculations and, accordingly, the thrust may be lost. If the machine does not pull, the reasons (VAZ-2110 injector including) may be in these sensors. If necessary, replace them, and then the power will return.
But if the car has an ECU, then why notis the corresponding lap on the dashboard lit? The electronic control unit is programmed for an open or short circuit. If this is not the case, and the sensor just does not work as it should, the computer will be able to report that the wrong mixture preparation process is in progress. If the machine pulls badly, there may be other causes, but the sensor should be checked. The source of the sensor's malfunctioning will have to be searched for independently. You can see the parameters of a particular element in the instruction.
Belt or timing chain
Crankshaft and camshaftmust rotate together and at the same time synchronously. To do this, use straps. Here you just need to combine the tags that are on the chains, belts and gears.It happens that the belt can jump to another tooth. Chains have the property of stretching. However, if these mechanisms are properly serviced on time, this reason can be excluded.
Exhaust system check
The device of the modern engine is quite complicated. Manufacturers make them so that cars do not pollute the environment. Or if polluted, then minimal.
So, one of the devices that affect cleaningexhaust gas, is a catalyst. It can be located in different places. If it is in your car, then with the regular use of low-quality fuel, which is sold in large numbers at most of our gas stations, the catalyst may become unusable. But it not only collapses, but can also block the normal exit of exhaust gases. As a result, the machine does not pull uphill. The reasons - including the clogged catalyst.
To test the catalyst, it is necessary to applyremote thermometers. You can also test its performance on the pressure in front of the device and after it. If all these options are not available, then you will have to dismantle the device and evaluate its status visually. If the catalyst is clogged, replace it or replace it with a flame arrester.
If the machine does not pull, the reasons may becompression. For testing, you will need a compressometer. It is better if it is equipped with a manometer with good accuracy. During operation of the motor, the piston rings are grinded off. As a result, the compression in the cylinders decreases or disappears altogether. If the valves of the gas distribution mechanism are not too tightly installed in their seats, then the test will show poor results.
To identify the cause of poor compression, afterThe measured measurement is added with oil to the cylinder, and then again measured. If the level is slightly increased, then it is necessary to change the piston rings. If no luck and compression remained the same, then the replacement will go to the valves. If the machine does not pull, the reasons (VAZ-2109 is no exception) can be just that.
Before measuring the compression, it is goodcharge the battery. Otherwise, you will not receive the correct figures. Compressometer screw in place of candles. It's much better than using a rubber seal. Perhaps, if the machine does not pull, the reasons for low compression.
Check the transmission
Sometimes the power unit can develop a seriouspower, but it does not reach the wheels. If during the ride you hear that the motor is working hard and no speed is felt, then maybe the automatic transmission system is stalled or there are blockages from the brakes.
To check, you must go straightsection, set the selector to the D position, and then see how the machine behaves. If the speed decreases, then the brake system must be diagnosed. If the brakes are all right, you need to go to a good service station and check the automatic transmission.
You can also check the parking brake. To do this, go to free space. Warm up the machine, and then pull the handbrake. Next, press the brake pedal, and set the box selector to D. Then push the accelerator. If the engine holds revs around 2000, then everything is in order. If less or more, you should go to the SRT to test the automatic transmission.
Why does not the machine pull: causes (carburetor)
If the traction of such an engine is lost, the fuel pump connection may be dirty or the system may have a low pressure.It is also possible that the carburetor is simply contaminatedor there are some problems with the needle valve. Errors or incorrect tune adjustment of the composition of the fuel mixture are possible. If the carburettor flap is not open enough, the traction may fail. When the fuel level in the engine is reduced, the thrust also disappears. When there are any problems with thrust in the engine, it is necessary to urgently conduct a full diagnosis.You have to find why it does not pull wellmachine, the reasons we have already considered. If a fault is found, immediately remove it. If you could not find the cause of the thrust yourself, do not hesitate. It is necessary to conduct a deeper examination in the SRT. But basically the cause still can be identified and eliminated independently.
So, we found out why the car has lost traction.
